1. Cerebrovascular diseases (CVDs) in humans are a mixture of diseases with different etiologies. 2. Although the stroke-prone spontaneously hypertensive rat (SHRSP) cannot represent all types of CVDs, it is probably a good genetic model for particular types such as lacunar infarction and intracerebral hemorrhage. 3. Genetic studies suggested that SHRSP has genetic susceptibility to stroke independent of its severe hypertension. Studies on SHRSP may provide useful information with which to dissect genetic susceptibility to particular types of CVDs.

Hypertension is a multifactorial and complex disease influenced by genetic and environmental factors, and it has become one of the most serious public health challenges. This study aimed to investigate the changes in hypertension based on urinary proteome. The stroke-prone spontaneously hypertensive rats (SHRSPs) model was used to examined urinary proteome changes during the development of hypertension.

Chronic hypertension is an increasingly prevalent condition that constitutes a risk factor for superimposed preeclampsia during pregnancy. In this study, we assessed the gut microbiome in a rat model of superimposed preeclampsia to characterize the microbial signature associated with defective placentation processes identified at the preclinical disease stage. The blood pressure profile, renal function parameters and fetal phenotype were evaluated in pregnant Stroke-prone Spontaneously Hypertensive Rats (SHRSP) and their normotensive controls.
View Article and Find Full Text PDFBackground: Chronic arterial hypertension restructures the vascular architecture of the brain, leading to a series of pathological responses that culminate in cerebral small-vessel disease. Pericytes respond dynamically to vascular challenges; however, how they manifest under the continuous strain of hypertension has not been elucidated.
Methods And Results: In this study, we characterized pericyte behavior alongside hypertensive states in the spontaneously hypertensive stroke-prone rat model, focusing on their phenotypic and metabolic transformation.

Inhibition of xanthine oxidoreductase (XOR) was shown to ameliorate the stroke susceptibility in the stroke-prone spontaneously hypertensive rat (SHRSP), suggesting hyperuricemia had a pathological role in this rat model. In this study, we thus aimed to explore mechanisms inducing hyperuricemia in SHRSP. XOR is known to have two forms, xanthine dehydrogenase (XDH) as the prototype and xanthine oxidase (XO) as the converted form through cleavage of a peptide bond or through formation of disulfide bonds in the enzyme.
